Fast breaking papers are publications that have the largest
percentage increase in citations in their field from one bimonthly update to the next.
The overlay method has two steps: (1) creating a global map of science as the
base map and (2) superimposing a specific set of publications, for example, from a
given institution or topic. Along with the method, the researchers have made a set
of tools available so that everyone could use their tools and generate his or her own
science overlay maps. The toolkit is freely available.
